Most digital clocks these days are made from microcontrollers, but I wanted an added challenge to use it using only logic chips trying to focus on using the TTL (74xx series) integrated circuits. So, my plan was to design and build a digital clock using…

My First Drone

I got a drone! I have waited forever to get a drone and I finally did it.

Once university had finished up for the year I had a little more time on my hands. I worked all the way up to Christmas saving every last penny I could as I had my eyes set on one big prize. I managed to save up enough money just in time to get it before the shops closed for the Christmas holidays. I literally spent ages researching and trying to figure out what drone to get for most of the year tossing up between a few different options and settled on the DJI Spark. It was only released in 2017 so it was relatively new but a perfect fit.

The DJI Spark is a tiny quad-copter weighing about 300 grams flight ready, which means it has the battery on and everything connected ready to take off and is about the size of an A5 piece of paper (143x143x55mm). The Spark is pretty quick too, with a top speed of 50 kph without any wind though, but I will say, even with the wind it’s still quite fast. The DJI Go app will warn you when the drone is battling high winds but will still allow you to fly the drone with caution. Flying in strong winds will shorten your flight time but with about 10-20 minutes of flight time, that’s enough to have some fun. If you get the Fly more combo you can get extra batteries and keep the fun rolling.

The camera isn’t the best quality but still is able to shoot in HD (1080p) and save that to the drone. Unfortunately, the video playback to your phone is worse and doesn’t record to your phone is HD but you will still be able to get the original shots off the SD card on the drone or through the DJI Go app. This means you can still get some high-definition pictures from the drone, but if you are using the drone specifically for aerial photography I would suggest one of the sparks bigger brothers, like the Mavic and Phantom. They have higher resolution cameras and are able to go higher and further than the spark.

I’ve taken my drone to heaps of different locations without it being an issue because of how small it is. The one thing that irks me is the range issue the spark has, with and without the dedicated controller. It never seems to perform as well as DJI quoted. But besides that, the spark is so much fun to fly. It is very nimble and quiet compared to the Mavic and phantom. I still can’t get over how powerful this little drone is. Check out some of the photos I’ve taken with it on my Instagram and let me know what you think!






I recently became a member of the University of Wollongong Motorsport (UOW Motorsport) team, which was a massive thing for me considering how much I like Motorsport. inside the Motorsport team I am working on building the brand new Electric vehicle (EV). This is the…

W100 Welcome

W100 Welcome

On Saturday the 8/04/2017 Westpac turned 200 years old. This was a momentous occasion, as it is Australia’s oldest business. Because it was such a big occasion Westpac decided to do something special and start up a foundation called The Westpac Bicentennial Foundation. Now creating foundations and charities was definitely not the new thing, but it the foundation provides grants to the people they believe will lead the way in Australia’s future. And again this isn’t the part that no one else has done, Westpac has set out to give out 100 scholarships, every year – Forever. That was the different part, the forever. Now imagine being part of the first 200 scholars that kicked off this foundation, pretty cool right?

Well I am one of those 200, and was welcomed into the W100 network just as Westpac is having its birthday.  How can you not be proud? I am one of 200 that kicked off the program as Westpac turned 200 and am the beginning of forever. I felt this was quite an achievement, being the start of something big. Who else could say they were there when it all began.

The welcome into the W100 network happened in two parts, a state welcome and the entire network welcome. The state welcome happened a couple of weeks ago with all the state scholars getting together to meet everyone in their state, so being a NSW scholar I met all of the other NSW scholars. I drove up to Sydney right after my last lecture on the Friday. I was pushing it for time to get to Sydney by 5pm. I went and picked up another fellow scholar and began the drive to Sydney. It wasn’t a very long drive only an hour and a half, but it was peak hour – which i wasn’t expecting driving into the city. the event was at a local lawn bowling club, so it was a pretty relaxed event. We had a unlimited bar tab and free food and bowls for the night. It was an awesome break from uni and this was just the beginning, the big two day summit was still to come.

On Thursday and Friday in early April, I, along with 100+ scholars arrived in Sydney for a massive summit. I was quite nervous, I had no idea what to expect, was there going to lots of people, or none at all? What events were we going to participate in? Most of the scholars arrived Thursday morning and a few arrived Wednesday night, as they were travelling from far far away land. The scholars were from all over Australia and traveling from Melbourne, Brisbane, Perth. Some of them waking up at 4 in the morning to fly over and be in Sydney. I don’t know how they managed to wake up at 4am, I can barely wake up at 8am to get to class on time.

I caught the train up with a few other scholars, as Wollongong is a short distance from Sydney. We arrived around 10am and walked from town hall to the hotel, carrying our bags. we checked in and went to check out our rooms. we all had our own rooms, queen beds, such an upgrade from university accommodation. After checking into our hotel for the night we walked over the the International Towers which is where the event was starting. It was just a short 5 minute walk down the street. on the way I walked part the Westpac Group headquarters, where it was being evacuated with 3 fire trucks sitting out side. Nothing appeared to be wrong, maybe just an exercise for the fire crew. There was also a group of people across the road from  the fire trucks, making cat noises and weird hand gestures. They were probably Westpac employees bored because they were stuck outside.

We were welcomed to one of the Westpac buildings at Baragaroo where we collected guest passes and our name tags. As everyone was just arriving in Sydney we all gathered in a foyer with snacks, chatting and getting to know each other before the summit officially kicked off. This was kinda awkward for me, as I knew one person and but it didn’t seem awkward for the future leaders as they went around meeting everyone.  The event started with all of us getting shuffled into a room on the 28th floor, with a stage set up the front. The bicentennial foundation CEO – Susan Bannigan, welcomed everyone and informed us of the plans for the next few days.

We split off into our scholarship streams, and headed off into different rooms in the tower. this was when I took the picture on the right, because I don’t think I’ve ever been this high up before. Now  was the time when we did the compulsory ice-breakers. They weren’t too bad this time because we only really did one, then socialised over food. We also learned about who the important people in Westpac are, just so we have an idea when we eventually meet them all. After lunch we went back up stairs to witness an interview with the SBS news presenter Lee Lin Chin.
The Westpac Group CEO – Brian Hartzer, spoke to all of us new people and gave us a little sneak peak into what to expect from Westpac. this was then followed by the only reason why half of us were here, the Lee Lin Chin exclusive. One of the 2016 scholars, was in-charge of running the interview. I don’t know if I could have done it, too intimidating. It was great to see an onscreen celebrity, in real life, and comparing the two. Lee Lin is almost just like she appears on TV. Her witty comments made everyone laugh, and it made me think that the massive wine glass was full of alcohol, instead of apple juice.

After this each stream split up again, to participate in an active learning session. My session was the one hosted by Julian O’Shea. Julian is a 2016 scholar and also the founder for Laika Academy. Just as the session was beginning we had afternoon tea, which was brownies and plenty of other healthier foods. after this was when we all played a massive game of scissors, paper, rock, with a twist. Every time you won you evolved into a new creature, then every time you lost you went back an evolution. and every time you met someone you had to introduce yourself and your degree. It was a very interesting way to meet my fellow scholars. the rest of the session involved creative thinking, new ways to come up with ideas, how to use the strengths of businesses to solve particular issues, and good old friendly competition.It was an awesome way to get to know the other scholars and realise the many different ways to innovate. After the sessions ended, everyone traveled back to the hotel, to freshen up and get ready for the awards ceremony in an hour. On the walk back I experienced more weird stuff as a smart car (extremely small two door hatchback) came rushing by with lights and sirens… it was an ambulance.

The awards ceremony was semi-informal event but with lots of formal attire. There was no assigned seating or anything but a stage, bar and live band, so it was more a party rather than an awards ceremony. This was when we officially became a part of the W100 network and were welcomed into Westpac. Each stream was introduced with each scholar having their image appear on the projection screen and receiving a W100 badge – yep it wasn’t official until we got the badge. After the stream presentations the food started rolling out, the band started playing, and the selfies began. Photos were being taken, left, right and center, capturing proof that we were actually here. This was also the time to meet as many people as you could: people from Westpac, scholars – anyone. It was essentially a great time to network.

I didn’t take too many photos but there are a few on my Instagram – Check them out @andy.wilkie
The next day started at 7:45am at the hotel where everyone gathered for breakfast, but I slept in like every other teenager would have done after being up late. So I don’t actually know what happened in the morning, l made it downstairs just in time for the group photo, but I assume the breakfast was good if the other meals were anything to go by. Now was the time to head over to our next destination, Carriageworks.

Carriageworks is an old train works warehouse that is used for events, and where the Westpac 200 years expo was set up. We put our bags down in one of the old work bays which had been converted into a cloak room, then sat down in front of a yet another stage. It kicked off with a welcome by some dude that I’ve never seen before, but that wasn’t why everyone was here. The speeches continued with one from Brian Hartzer, all followed by an imagination lecture. The imagination lecture was by none other than the co-founder of Netflix, Marc Randolph. He talked about how he got started including his meeting with Blockbuster and how Netflix has “gotta crush them”. He also discussed some key ideas about how to run a business, what defines a good idea, and how you have to take risks to be successful. It was interesting to hear the struggles he went through, how many companies he has helped start up.

The audience wasn’t just scholars, it was also businesses of the future and other randoms, but it was very exclusive. It was pretty cool being chauffeured around Sydney and being treated like someone important, especially at the age of 18. the scholars were set free and allowed exclusive access to the Westpac 200 Years exhibition, before the public. The expo was split into 3 sections: first, second, and third centuries. Which was basically the past, present and future for Westpac, where they came from, what they do now, and what they want to do. The third century was my favourite, it had all of the exciting future technology in it. It also had a section dedicated to scholarship program. It was awesome seeing a panel with the first 200 scholar names written on it. Eventually the exhibition will pack up and travel all around Australia, and then be set up in a permanent location, probably in Sydney somewhere. It also include heaps of the technology that is being released and yet to be released, including cool things like, augmented reality and unmanned aerial vehicles. All of this happened before lunch, so the next item on the agenda was food.


All of the scholars gathered in some random area of carriage works, where a bunch of tables and yet another stage was set up. It was strange having a stage set up in almost every room we went into. We had more inspirational speeches, from 2016 scholars and Susan Bannigan, during lunch as we started to wrap up the event. The only thing I was really thinking about at the time was how many brownies can I get without seeming greedy. I think I got about 4, so that was approximately 12 brownies for the entire 2 days. As the brownies started disappearing was when Susan got back on the stage and began thanking everyone, handing out gifts to the helpers. It was kind of sad that it was the end. It was so much fun having an entire event dedicated to you and 99 other special people.  But it was the end of 2 action packed days of excited events, and free food. We were all promptly scooted out of carriage works, grabbing back and scrambling around to make it onto buses to get to the airport, but of course not after we grabbed the heaviest book they could possibly give us, a copy of  The Westpac Story. I’m yet to look at it, but it has plenty of pictures. Luckily for my and the other Wollongong and Sydney scholars, we only had a 10 minute walk to the train station and plenty of time to return home.

Overall it was awesome! I thoroughly enjoyed meeting other like-minded people, famous people, people that have changed the world and just generally cool people. Oh and not to forget, the free brownies were pretty good. I would definitely do it again if given the opportunity, but who knows this might lead to working over in America for a big tech company because they know Westpac, who knows what is next to come.



Welcome to UOW

Welcome to UOW

Creating a Website

Creating a Website

This is the my first website that I have published, and this is how I went about creating it all.




We arrived in Rankin Springs, NSW on Thursday night after a long 4 hour drive. We quickly set up camp as light was fading so as to avoid getting too many mosquito bites, set up our temporary workshop and made last minute fixes until 1AM both code and hardware.

Early the next morning (04 November 2016) we had breakfast kindly made for us by Rankin Springs Primary School, before crossing the road to launch in an open space. We encountered a few delays fixing last minute bugs and problems such as fitting everything into the case without breaking anything, as well as attaching extra tracking equipment that allowed us to track the payload in real time.

Last minute fixes
Signed and everything


We began filling the balloon at 11am and released it at 11:30am. A slight down-draft caught it at first, but it rose into the sky quickly, reaching 1km in less than 5 minutes.

After ensuring the radios were functioning, allowing the 3 cars of our group could communicate with each other, the chase began. While tracking it in real time, we followed the balloon along the closest roads we could find. This lasted for 2 hours, as the balloon rose through the layers of the atmosphere, bursting at 1:23pm at 30,000 metres altitude. The descent took 30 minutes, which was a lot quicker than we were expecting making us believe the parachute failed to deploy. The payload landed at 1:50pm in a wheat field. It travelled over 100km away from the launch-site.


At least it didn’t break when it landed

We found it half an hour later, and, thankfully, a dirt road took us as close as 100 metres to it.

The payload had landed safely thanks to the protection of the case, with even the rudder still intact. The balloon however… we cannot say the same for.

Unfortunately, when it hit the ground our components became disconnected, and we were unable to collect all of the data we had wanted. However it still makes for some amazing footage.

Thank you to the local primary school for making us breakfast and lunch and a big thank you to Robert for making this all a possibility. It has been an amazing experience and a pleasure to finally see our hard work put into action, and it has been a pleasure working with the G(A)SP team on this project, you nerds.
